1 Claim.

This invention relates to a combination weather strip and window sash control construction, in-' tended to prevent the entrance of cold air when the sash is down, and which will hold the sash in any raised or lowered position and permit the easy movement of the sash by hand.

More particularly, this invention is an association of sash Weatherstripping and'sash control devices having special construction and arrange.- ment'as set forth in this specification. It is believed that the structure and disposition of the parts described inthis application will reduce the amount of metal needed in window sash controls and do away with the use of sash weights and cords, thereby lessening the cost oi manufacture of like window control devices.

Of the accompanying drawing intended to illustrate this invention and forming a part of this applicatiomFig. 1 is a front view of a lower window sash and frame with this invention applied thereto.

Fig. 2 is a horizontal sectional viewof a portion of the window frame and sash taken on the line 2- -2 of Fig. 1. Y Fig. 3 is a horizontal sectional view of a portion of a window frame. and sash taken on the line 33 of Fig. 1.

Fig. 4 is a top plan' view of one of the grooved,

resilient metal pieces hereinafter described.

Fig. 5 represents asectional view lengthwise of the metal piece shown in Fig. 4.

Throughout the drawing and description the same number is used to refer tothe same part.

The window frame I, sill 2 and glass 3 may be of any usual construction. The applicant does not intend to limit the construction of those parts in'anymanner.

1 or screw of common form. The spring metal pieces are usually the same in length as the sides of the sash to which they are attached.

Ihe grooved portion of the piece is intended to the weather strip in Fig. 3.

As illustrated in both Figs. 4 and 5 two portions have the length of Weatherstripping secured therein in any manner. The number 8 refers to It will be understood from Fig. 4 that the view is taken looking into the longitudinal groove 5 which is continuous for the length of the piece.

near the ends of the piece are partly detached from the flanges of the piece and formed into raised springs 9. Usually there is only the two curved raised springs 9, but it may be advantageous and necessary in some windows to have more than two spring elements 9 formed in the flanges of each piece. If the grooved middle 5 of the metal piece is inserted in the groove in the sash, with the Weatherstrip 8 therein, the integral springs 9 of the pieces will press against the frame I and hold the sash in any raised position. In other words, a single piece of spring metal attached on each side of the sash, with a series of curved springs formed in the piece holds the sash in any raised position, carries the Weatherstrip, and the onlyv necessary weatherstrip-is thatheld by the metal piece in the side of the sash, and moving up and down with the sash. l

Having now described this invention, I claim: In a combination weather strip and window sash control apparatus, a sash having a vertical groove on each side, continuous longitudinally grooved pieces of spring metal each having side flanges attached to the sides of the sash, the grooved portions engaging the grooves in the sash, said pieces of spring metal being constructed with spaced curved resilient portions having one end separated from the continuous piece and arranged to press against the window frame, and weather stripping attached in the grooves of said pieces of metal and arranged to move up and down'with the sash.
